Question

我有一个项目，我需要将表单AS2更新为AS3，因为我需要一些可用于垂直居中文本的新功能。

我在时间线上的当前AS2代码如下。

var dataField =  _root.dataField;
var dataType =  _root.dataType;
var dataPage =  _root.dataPage;
var dataVar =  _root.dataVar;
_root.mc.onRelease = function() {
    getURL("index.php?page="+dataPage+"&num="+dataNum+"&"+dataType+"="+dataVar, "_self");
};

我的外部AS文件如下。

import mx.transitions.Tween;

/**
 *
 *  StandardKey is attached to a movieclip in the library.
 *  It handles the basic button behavior of the keyboard keys.
 *  When each button is placed on the stage, it's instance name
 *  will be the unique ID of the key.
 *
 */
class StandardKey extends MovieClip {


    ///////////////////////////////////////

    //Stage Elements    
    var highlight:MovieClip;
    //End Stage Elements
    var highlightTween:Tween;

    function StandardKey(Void) {
                //Repaint the key with 0 alpha
        highlight._alpha = 0;
    }


    function onPress(Void):Void {

        //Do the highlight animation
        highlightTween.stop();
        highlightTween = new Tween(highlight, "_alpha", mx.transitions.easing.Regular.easeInOut, 100, 0, 10, false);
    }

}

这是我尝试将时间轴和外部AS2移动到AS3

时间轴我现在有：

var dataField =  this.dataField;
var dataType =  this.dataType;
var dataPage =  this.dataPage;
var dataVar =  this.dataVar;
var dataNum =  this.dataNum;
_root.mc.onRelease = function() {
navigateToURL(new URLRequest("index.php?page="+dataPage+"&num="+dataNum+"&"+dataType+"="+dataVar, "_self"));
};

我有外部AS3

package {
import fl.transitions.Tween;
import fl.transitions.easing.*;
import flash.display.MovieClip;

/**
 *
 *  StandardKey is attached to a movieclip in the library.
 *  It handles the basic button behavior of the keyboard keys.
 *  When each button is placed on the stage, it's instance name
 *  will be the unique ID of the key.
 *
 */
public class StandardKey extends MovieClip {


    ///////////////////////////////////////

    //Stage Elements    
    var highlight:MovieClip;
    //End Stage Elements
    var highlightTween:Tween;

    public function StandardKey(Void) {
                //Repaint the key with 0 alpha
        highlight._alpha = 0;
    }


    public function onPress(Void):void {

        //Do the highlight animation
        highlightTween.stop();
        highlightTween = new Tween(highlight, "_alpha", fl.transitions.easing.Regular.easeInOut, 100, 0, 10, false);
    }

}
}

我目前得到的错误是：

场景1，图层'标签'，第1帧，第6行1120：访问未定义的属性_root。场景1，图层'标签'，第1帧，第7行1137：参数数量不正确。预计不超过1个。

如果有人能帮我解决这个问题，我会非常感激。

亲切的问候垫。

Answer 1

不要使用_root，如果你绝对需要向上引用，那么最接近的AS3等价物就是阶段。

DisplayObject属性不再以下划线开头（在您的情况下为_alpha与alpha。）

你不能使用onRelease，你需要使用addEventListener（）

你的时间轴代码没什么意义，为什么你要制作本地变量呢？

总而言之，我建议你阅读Adobe's migration guide。

Answer 2

变化

_root.mc.onRelease = function() {
navigateToURL(new URLRequest("index.php?page="+dataPage+"&num="+dataNum+"&"+dataType+"="+dataVar, "_self"));
}

到

mc.addEventListener(MouseEvent.CLICK, mcClicked)
function mcClicked(e:Event) {
    navigateToURL(new URLRequest("index.php?page="+dataPage+"&num="+dataNum+"&"+dataType+"="+dataVar, "_self"));
}

highlight._alpha = 0;至highlight.alpha = 0;

highlightTween = new Tween(highlight, "_alpha", fl.transitions.easing.Regular.easeInOut, 100, 0, 10, false);

到

highlightTween = new Tween(highlight, "alpha", Regular.easeInOut, 100, 0, 10, false);
